Hey Bird of Prey! Don't worry, It took me a month to figure this out so I'll pass on the knowledge to you. In you command console (shift +tilda) if your not familiar with that. Type in exactly Bind (key) say..............your text
Just bind whatever key u want to use but don't put the ( ) around it. That was just for writing purposes. There you go and I hope that helps you write some messages
